8 week old not eating

[babysmama]

In the last 2 days my 8 week old has refused eating,  going from 4 oz every 4 hours to 1-2 every 3.5-4 hours. I am not sure what is causing this, but he has also refused to also nap, staying awake for up to 7 hours. So do you think his lack of sleep is the cause of him not wanting to eat? Anyone else experience this? Also during the feeding he cries the entire time, like he is totally exhausted. Could this be a growth spurt?

My first question would be if he is gaining weight?  Spitting up or Vomiting?  Does he have reflux?  Has the food changed?

I would definitely suggest checking out the reflux boards and see if any of the symptoms sound like your lo.  My DD was a champ feeder and then all of a sudden started refusing feeds and screaming etc, looked on the boards, and it turned out she had reflux

Also have you checked in your lo's mouth, to make sure he does not have thrush in his mouth.  This can be very painful and could also be a reason why he is refusing to feed.

Hugs hun, hope things improve for you
